For companies in the manufacturing industry, working with the right standards is not a minor concern — it is an essential part of operating safely and responsibly. Yet for many organizations, it is not always clear which NEN standards apply to their specific situation, how to determine this, and what is expected of them. In this article, we answer the most frequently asked questions about NEN standards, so you as a business owner know exactly where you stand.
What are NEN standards and why are they important?
NEN standards are national standards drawn up and maintained by the Royal Netherlands Standardization Institute (NEN). They describe technical requirements, safety standards, and quality guidelines for products, processes, and services. Companies that comply with NEN standards demonstrate that they operate in accordance with recognized and validated benchmarks within their field.
The importance of NEN standards goes beyond a paper obligation. They contribute to employee safety, the reliability of installations, and the quality of products. In addition, standards provide a common language between suppliers, clients, and regulators. Companies that demonstrably comply with the relevant NEN standards build trust in the market and reduce the risk of incidents, liability, and costly downtime.
Which NEN standards apply to the manufacturing industry?
In the manufacturing industry, multiple NEN standards apply, depending on the type of product, the materials used, and the working environment. The most relevant standards relate to structural safety, mechanical engineering, electrical installations, welding, and lifting and hoisting equipment. These include the NEN-EN series that align with European directives such as the Machinery Directive.
Concrete examples of relevant standards areas for the manufacturing industry include:
- NEN-EN ISO 3834 for quality requirements in the welding of metal structures
- NEN-EN 1090 for the execution of steel and aluminium structures
- NEN-EN 60204 for the electrical equipment of machinery
- NEN-EN 13001 for the design and calculation of crane structures
- NEN-EN 14492 for powered winches and hoists
The manufacturing industry also frequently works with standards derived from European directives, which means the distinction between national and European standards is small in practice. NEN-EN standards are national implementations of European standards and therefore serve as the applicable benchmark in the Netherlands.
How do you determine which NEN standards apply to your company?
You determine which NEN standards apply by looking at three factors: the sector in which you operate, the products or installations you manufacture or use, and the laws and regulations you must comply with. Start with the relevant European directives for your industry, then look up the corresponding harmonized standards.
A practical approach consists of the following steps:
- Identify the applicable EU directives for your product or activity, such as the Machinery Directive, the Low Voltage Directive, or the Pressure Equipment Directive.
- Consult NEN’s standards overview via the website of the Royal Netherlands Standardization Institute, where you can look up the harmonized standards for each directive.
- Engage a technical advisor or inspection body with knowledge of your industry who can interpret the specific standards in the context of your business processes.
- Record the findings in a standards overview or risk analysis, so you can always demonstrate which standards you have identified and how you comply with them.
It is advisable to repeat this process periodically, especially when introducing new products, modifying production processes, or when standards are revised.
What is the difference between mandatory and voluntary NEN standards?
Mandatory NEN standards are standards that have been declared legally binding through legislation or regulation. Voluntary NEN standards are technical guidelines that you are not legally required to apply, but which are recognized as the accepted benchmark in practice. The distinction lies not in the standard itself, but in the way the government or a client refers to it.
A standard becomes mandatory when a legal provision — such as a European directive or a national decree — explicitly references that standard. In that case, compliance with the standard is a legal requirement. If you do not comply, you must demonstrate in another way that you meet the underlying legal requirements, which is considerably more complex in practice.
Voluntary standards are technically optional, but are used as the de facto benchmark in many sectors. Clients, insurers, and inspection bodies frequently use them as a reference framework. In practice, this means that deviating from a voluntary standard requires justification and can sometimes carry commercial or liability risks.
Which NEN standards apply specifically to crane systems?
Specific NEN-EN standards apply to crane systems, covering design, manufacture, installation, operation, and periodic inspection. The most central series is NEN-EN 13001, which describes the design principles for crane structures. In addition, standards for electrical drives, lifting equipment, and safety components apply.
The most important standards for crane systems are:
- NEN-EN 13001 (parts 1 through 3): Crane safety, general design principles, including loads and load combinations
- NEN-EN 15011: Specifically for bridge cranes and gantry cranes
- NEN-EN 14492: Powered winches and hoists
- NEN-EN 13135: Requirements for crane equipment and components
- NEN-EN 13157: Manually operated lifting equipment
- NEN-EN 12644: Information for the use and periodic examination of cranes
In addition to the structural standards, the Machinery Directive (2006/42/EC) plays a central role, as cranes are classified as machinery and must therefore meet the essential health and safety requirements of that directive. We design and build our crane systems in full accordance with these standards, so customers can rely on installations that meet all applicable requirements.
How do you stay informed about changes to NEN standards?
You stay informed about changes to NEN standards by signing up for updates through the Royal Netherlands Standardization Institute, following relevant industry associations, and working with suppliers and inspection bodies that actively monitor changes to standards. Standards are revised periodically — typically every five years — and it is your responsibility as a company to use current versions.
Practical ways to keep track of changes to standards:
- NEN subscription or standards package: Through NEN, you can subscribe to specific standards or standards areas, so you automatically receive a notification when revisions are made.
- Industry associations: Organizations such as FME (for the technology industry) or Verticaal Transport (for hoisting and lifting equipment) keep members informed about relevant changes to standards.
- Technical partners and suppliers: Working with parties that use these standards on a daily basis ensures that changes to standards quickly find their way into your business processes.
- Internal standards manager: Larger organizations appoint a staff member responsible for monitoring and implementing changes to standards.
Identifying changes to standards in a timely manner is not just a matter of compliance — it also gives you the space to implement adjustments to design, production, or documentation carefully and without time pressure. As a recognized inspection and certification partner, we always work with the most current standards, ensuring that the crane systems we deliver and inspect are fully up to date with the applicable benchmarks.

Frequently Asked Questions
What happens if my company does not comply with mandatory NEN standards?
If you do not comply with mandatory NEN standards, you risk legal liability, fines, and the shutdown of production processes by regulators. It can also lead to problems with insurers or clients who require compliance as a contractual condition.
How often do I need to have my crane systems inspected according to NEN standards?
The inspection frequency for crane systems depends on the type of crane, the intensity of use, and the applicable standards such as NEN-EN 12644. In most cases, an annual periodic inspection applies, but more frequent inspections may be required under intensive use or special circumstances.
Can I determine myself whether my installation complies with NEN standards, or do I need an external party for that?
You can draw up a standards overview and risk analysis internally to some extent, but for formal assessment and certification you generally need a recognized inspection body or certification partner. They have the technical expertise and accreditation to demonstrate compliance to clients and regulators.
Do the same NEN standards apply if I export crane systems to other EU countries?
NEN-EN standards are national implementations of European standards and therefore apply in all EU member states that have adopted the same EN standard. As long as your crane systems comply with the relevant NEN-EN standards and the Machinery Directive, you are in principle also compliant for the rest of the EU market.
